' ,VEHICLE-WHEEL.

To all whom t may concern Be it known that l, DANIEL MoRIARTY,

a citizen of the United States, residing atV Oakland, in the county ofAlameda and State of California, have invented new and usefulImprovements in Vehicle-Wheels, of which the following is aSpecification My present invention relates to improvements in vehiclewheels, and more especially to those vof the type adapted for useu'ponautomobiles, motor trucks and the likehaving resilient means interposedbetween its inner portion and its outer or tire-carrying felly wherebysolid tires maybe used elli ciently and the requisite amount ofresilienceouter felly which carries the tire. Prefer will be securedfrom within the wheel.

The objects of the invention are to provide a generally improvedstructure for re` silient wheels of such type and to provide an improvedmode of mounting Vand securing the tire upon the outerrim or fellywhereby loosening and breakage `ofthe tire are effectually prevented. A

To these Vand other ends, the invention consists in certainimprovements, and com`4 binations and arrangementsof parts, all as willbe hereinafter more fully described, the

novel features being pointed out p articularlyV in the claims at the endof the specification ln the accompanying drawings:

Figure 1 is aside elevation of a vresilientvehicle rwheel constructed inaccordancefwith the present invention. i

Fig. 2 is a side elevation, partly in section, of a Section of thewheel; and

Figs, 3 `and et represent sections on the lines 3 3 and 1--4respectively `of Fig'lQ.

Similar parts are designatedby the same reference characters intheseveral views.

The present improvements are applicable generally to vehicle wheelsalthough they are particularly applicable to wheels such as used uponautomobiles and motor trucks. The preferred embodiment of the inventionis shown in the accompanying drawings and will be hereinafter describedin detail, but it is to be understood that equivalent constructions arecontemplated and will be included within the scope of the claims.

In the present instance the invention is applied to a wheel whichcomprises a hub 1 which may be 0f the usual construction and to whichthe spokes 2 are secured rigidly, the outer ends of the spokes beingfixed in an inner continuous felly 3 which may be of wood, as usual, orof other suitable conl Specification 4o1! `lElatent. i `PgjljgenigedAug, 1919,V Application nea october 31, 1917. serial No. 199,517.

struction. `A ccordingto the present inven tion, an outer felly t isprovided which is composed of wood or other suitable material and 1sannular or endless in form, its ends being joined and secured firmlytogether by plates l 5 which lap the joint and bolts 6 which-extendthrough the plates and bind them i firmly to the respective ends oftheouter felly. The outer felly is of adiameter greater than that of theinner felly, thus providing an annular spiace between the fellies, andthis Vspace is provided Vfor the purpose of accomnnodating` a cushionwhich affords the requisiteresilience between the hub or inner sectionof the wheel andthe Vouter fellies and it is capable of sustaining thenormal load upon the wheel which vacts to move the inner felly at thelower side of the x wheel downwardly. The cushion will also yield,more'or less,to absorb abnormal pres sure exerted by the inner fellythereon due te irregularities inthe surface over which the wheel rollsor travels.-

`The outerxfellyA is retained inl coperative relationwithftheinner`felly by segmental plates Swhich are secured to the inner and outerfellies and are suitably spaced circumf ferentially" thereof.`Preferably, and as shown, these plates at the opposite sides of thewheel are arrangedin pairs, they being lclamped securely at their innerends to the opposite sides of the inner felly 3 by a bolt 9 whichextends through the plates and through the felly, and the outer ends ofthe plates of each pair are arranged at the opposite sides of the outerfelly 4 and they are prevented from spreading by a bolt 10 which fitstightly into the outer felly and extends loosely through4 apertures 11in the plates, the bolt having a head 12 at one end to lie against theouter side of one of the plates and a nut 13 adjustably applied to itsopposite end and lying against the other plate, a cotter pin 14 beingpreferably fitted through the nut and through the bolt to preventloosening of the nut after it has been adjusted. With this arrangementthe plates are fined rigidly to the inner fellybut relative movement mayoccur between the plates and the outer felly 4L. Preferably, theintermediate portions 15 of the plates/ are bowed or bulged in order topermitlateral spreading ofjthe' cushion when the latter is compressed ina radial direction.

The present invention also provides improved means for `mounting andsecuring va solid rubber tire upon the outer felly. As shown, an endlessmetal band 16 is fitted tightly upon the outer periphery of the outerfelly 4, it being `preferably secured thereto by a suitable numberofradialbolts 17 which extend outwardly throughthe inner felly andthrough the metal band, and a cap nut 18 is applied to the outer end ofeach of these anchor bolts. A number of pins 19, preferably of metal,are driven through holes in the metal band 16 into the outer felly 4,the outer ends of these pins projecting beyond the outer side of themetal band 16. A layer of gutta-perchaor similar hardrubber 20 isvulcanized to the outer surface of the metal band 16 in such a way thatthe pins 19 are embedded infthis gutta-percha layer and, preferably, thepins project some distance beyond the outer periphery of thegutta-percha strip or layer. The solid rubber tire 21 which is composedyof a suitable rubber .compound such, for eX- ample, as that commonly`used upon ordinary solid ties, is then vulcanized to the outer surfaceof the strip or layer 20 of gutta-percha or hard rubber. This mode ofmounting and securing thesolid tire upon the outer felly insures a firmhold 4between the tire and the felly and it -will prevent loosening andconsequent breakage of the tire, the rubber compound of the tire beingfirmly united by vulcanization tothe gui/tapercha or'hard rubberstrip orlayerand the gutta-percha `layer lbeing' firmly Secured to themetaliband 16, and the pins 19 firmly secure the rubber tire tothegutta-percha or hard `rubber layer and they firmlylunite the tire andthe gutta-percha layer to the felly.

'The present invention provides a vehicle wheel which is capable offulfilling the severe conditions imposed thereon when used uponautomobiles and motor trucks, particularly when solid tires are used,the necessary amountof resilience being afforded by the infiated orpneumatic cushion to 'insure easy riding properties V and to absorbShocks due to irregularities in the road surface,and while theresilience of the pneumatic cushion is obtained, yet the pneumaticcushion is not subject to puncture or wear. The present invention alsoprovides an improved mode Qf'mounting a solid tire upon Athe rim orouter felly of the wheel whereby loosening andconsequent breakageofthe'tire, as commonly occurs with solid tires as lheretofore applied,are avoided.

I claim-as my invention: 1. In a vehiclewheel, thecombination of afelly, a metal rim, dowel pins embedded and secured in the felly andextending through and `projecting outwardly beyond said rim, acircumferential strip of hard rubber vulcanized to the outer peripheryTof the metal rim and to said dowel pins, and a tire vulcanized to theouter side .of said hard rubber strip.

2. The combination of a metal rim, a plurality of metal pins fixed inthe rim and proj ecting'radially outwardlytherefrom, a circumferentialstrip of hard rubber vulcanized to the pin-carrying rim, the pinsprojecting outwardly beyond the hard rubber, and a rubber tirevulcanized tothe outer side ofsaid hard rubber and having saidprojecting portions of the pins secured therein.

In testimony whereofI have hereunto set my hand in presence of twosubscribing witnesses.

DANIEL MORIARTY.
